i&| LECTURES AND ESSAYS not give MS the right to say that it is true. And the question which our conscience is always asking about that which we are tempted to believe is not, "Is it comfortable and pleasant?" but, "Is it true?" That the Prophet preached certain doctrines, and pre- dicted that spiritual comfort would be found in them, proves only his sympathy with human nature and his knowledge of it; but it does not prove his superhuman knowledge of theology. And if we admit for the sake of argument (for it seems that we cannot do more) that the progress made by Moslem nations in certain cases was really due to the system formed and sent forth into the world by Mohammed, we are not at liberty to conclude from this that he was inspired to declare the truth about things which we cannot verify. We are only at liberty to infer the excellence of his moral precepts, or of the means which he devised for so working upon men so as to get them obeyed, or of the social and political machinery which he set up, And it would require a great amount of careful examination into the history of those nations to determine which of these things had the greater share in the result So that here again it is the Prophet's knowledge of human nature, and his sympathy with it, that are verified ; not his divine inspiration or his knowledge of theology.
